OpenGL图形系统是一个软件接口，让程序员能够创建交互式程序，使用计算机图形学技术生成具有真实感的图像。本书是OpenGL ARB推荐的OpenGL 1.4版学习指南。

　　本书首先阐述OpenGL的功能和计算机图形学基本知识，包括状态管理和几何体的绘制、模型变换、视点变换和投影变换、颜色和光照；然后深入探讨一些高级技术，包括反走样、混合、雾效、显示列表、图像处理、纹理映射、帧缓存、网格化、NURBS、选择和反馈等；同时讨论其他一些重要主题，像如何提高程序的性能、OpenGL扩展和跨平台技术等。

-OpenGL graphics system is a software interface that allows programmers to create interactive programs that use computer graphics technology to generate a realistic image. This book is recommended by the OpenGL ARB OpenGL 1.4 version of the study guide.

This book begins by describing the features of OpenGL and basic knowledge of computer graphics, including state management and the geometry of the drawing, model transformation, perspective transformation and projection transformation, color and light　and in-depth look at some advanced technologies, including anti-aliasing, blending, fog , the display list, image processing, texture mapping, frame buffer, grid, NURBS, selection and feedback　also discuss other important topics, like how to improve program performance, OpenGL extensions and cross-platform technology.
